Only started playing LiS a couple months ago. I finished BTS a couple days ago. The endings to both games hit me really hard, BTS even more so.
I'm still not fully over it. I can't look at Chloe or Max, or hear any of the dialogue without getting some sort of post-series depression or something lol. I don't even want to play LiS 2, I don't really care about anyone else but Chloe and Max. Apparently there's an official LiS comic that continues the two's story after the 'Sacrifice Arcadia Bay' ending so I'll have to look into that but yeah, it hit me hard.
This is exactly how I feel.
Comics are good, at least the fact that they're sanctioned by Square makes me feel like that's the canon finale. But I found some of the fanfic better than the comics, tbh.
